[SP7P] Downgrade failure: "No supported devices found" #36

Closed Pairman closed 9 months ago

Pairman commented 9 months ago

Hello. I'm using repack.sh to downgrade UEFI firmware for my Surface Pro 7+, to boot Fedora installation successfully. I'm using a Fedora 39 live CD with Ventoy to do this. Repacking is successful, but installation says "No supported devices found".

This is my environment:

The original cab comes from https://www.catalog.update.microsoft.com/Search.aspx?q=22.102.143.0 (whose version number comes from https://support.microsoft.com/en-us/surface/surface-pro-7-update-history-fc2c14a8-0e72-4acc-851d-ae96f608c397 ). It was then repacked successfully:

./repack.sh 12ed8dd6-1131-4fb4-a9a6-0b33cf2dc006_5513e857d2cc8b01cadca69bc0b35e9ca52ed4d8.cab

==> Repacking ./tmp.4m73E6ReY9/SurfaceUEFI.inf
Success!
If you wish, you may now install the firmware like so:

  sudo fwupdmgr install --allow-older --allow-reinstall --no-reboot-check --force 'fwupdates/tmp.4m73E6ReY9_22.0.26255_371f28d9-5d0f-49f1-a61a-3f16e3c53506.cab'

But the installation failed:

Details of the output cab file says "Unknown Device", other than "UEFI Firmware" (or something similar, sorry for forgetting to save sudo fwupdmgr get-devices logs):

The SP7+ is f3e47718-bcbb-4691-b67f-5408c8f8105f and not 371f28d9-5d0f-49f1-a61a-3f16e3c53506, checked by downloading the full driver MSI bundle and repacking it.

You can get all available cab files by searching for UEFI\RES_{f3e47718-bcbb-4691-b67f-5408c8f8105f} on the MS Catalog.

But that doesn't give you 22.102.143.0, only 22.103.143.0 and newer, plus a bunch of older versions. Maybe 22.102.143.0 was released only on Windows Insiders and never went out to Windows Update? In that case the Catalog wouldn't have it.

Thanks! I used Surface - Firmware - 18.200.143.0 from the search results and installed successfully.
